A gyroscope's behavior tells us that this 'multiple axes of rotation' will not exist. Even without all that freedom a bike wheel spinning in our hands tells us 'no'. Then coming down to math, what do we have? We can give up mass at this level, and if we want to discuss a solid object and its many possible orientations then we have no problem, but when we attemp to superimpose two simultaneous rotational axes onto one object I believe we witness a noncomuttative property. I may stand to be corrected here, but I'll try to expound on why I think that this is so. In order to even declare a single rotational axis on an object we will be forced to select two point positions (for a three dimensional object) as forming the axis, and to specify a distict amount of rotation we might take a third point and expose it's traverse. To declare a second rotation we should repeat the steps of the first selection, but with unique points. These then are two independently defined rotational axes, each acceptable on its own terms. If we perform the first rotation, then perform the second rotation then we should witness the object's traverse over those discrete rotations. When we perform the second rotation then the first rotation we witness a new position different from the first commutation of the operation. I am reasonably comfortable verifying this with a mug with a handle on it here at my desk, performing two 90 degree rotations. > > Thinking about this longer, doesn't rotation imply restoration?

It's a tad abstract. Hmmm. To define the spin on an object from outside carefully would be helpful. Above I've tried it in a way that is coherent to the object. Anyway, these exercises are free aren't they? If you wound up with a coherent model of how that sphere's 'atoms' rearranged themselves you could well wind up with a new theory of atoms. Whether to remain in the physical or recover the physical from a seemingly ambiguos definition... I'd try for the latter, but have a hard time getting away from the former. > > Then there's the circular saw.

Nice, and we do actually have the ability to control the orientation of that saw with a good amount of freedom, though the forces involved may be a bit trickier than we realize when doing that. It's not as if we're caught in a precession that will not end, cutting aside.

From: spudnik on 28 May 2010 17:25 as Tim LocquaciousHand implies, "composition" of two rotations, one after the other, is not commutative, as the demonstration also can be modeled with quaternion multiplications; in any case, two roatations resolve into one, about a different axis. the question is, if you try to do them simultaneously, what happens? and, please, see if you can show it with quaternions, instead of this interminable blabfest; thank *you*. thusNso: Dear woould-be replacer of Jerry "no oil, except from Texas etc." Brown: no change from Jerry Brown's '69 "platform," eh? it is intolerably stupid, insofar as we do need "fossilized fuels TM (sik)," to not get our share from our own "reserves." really, though, it is merely biomass, and the techniques have progressed since '69. Dubya's bro's ban offshore of Florida (and Louisiana) seemed like a tactical maneuver to support the oilcos' scarcity programme in our state. (why O why O why do folks believe, that the oilcos did not support the Kyoto Protoccol, which was just another cap'n'trade "free trade" nostrum, that Dubya'd have undoubtdely signed, if he had been told?) British Petroleum, the balls-out advocate of cap'n'trade, "Beyond Petroleum," is also the biggest company in the Alaska North Slope -- doesn't any body wonder, why no-one asked Palin about her BP-employed hubbie, and his Seccesionist ideals? one must take into consideration, with all of the hype about it, that oil comes out of the ground underwater in "seeps," under pressure. so, how much would come out, if BP et al ad vomitorium were not pumping like crazy? Waxman's current cap'n'trade bill just mandatorizes the huge, voluntary cap'n'trade since 2003 -- tens of billions in hedging per annum. what the Liberal Media (Ownwd by consWervative) don't talk about, is that he brought the first cap'n'trade bill in '91, under HW (who worked with Gore on the Kyoto cap'n'trade). what it amounts to, as Waxman basically admitted to, when he was at UCLA, is "let the arbitrageurs raise the price of energy, as much as they can in the 'free market' -- free beer, freedom!" a small, adjustable carbon tax would achieve the same ends -- as I even read "in passing" in a guest editorial in the WSUrinal, as well as from an "expert" in a UCLA seminar, but who said that it was (some how) "politically impossible" -- without being the Last Bailout of Wall Street (an the City of London). thusNso: I never read a word about Palin's hubbie's Seccesh "movement" in the Liberal Media (Owned by consWervatives) and that is sort-of the issue in AZ. I'm all for kids whose parents managed to sneak across the border & give birth, but I was taken aback by the "sense of entitlement" that the older kids have, about college (the DREAM Act; I stated to a group of them, that crossing the border is essentially a Mexican "rite of passage," and it is certainly not very dangerous as a proper hike, if you check the FAQs and maps & so forth from the Mexican goment (and those advocacy/ haven groups in the USA; it may be difficult in the summer, though). well, it's either that or college *in* Mexico, or you'll probably be made to join a gang. La Raza d'Atzlan are openly racist, not just by their title; at least, that's the impression that I got, attending one of their meetings at UCLA, two or three years ago -- it's in their God-am constitution. of course, teh real problem is "free trade," and this is already here to roost; the little spill in the Gulf is being used by British Petroleum -- which is also the #1 driller in the Alaska North Slope, that Ted Palin works for -- to create an "outsourcing" mandate to solve the problem, because we can't do it with our post-industrial cargo cult. well, iscrew that! read LaRouche, if you want to know the history with Lincoln and his "Spot Resolutions;" Cinco de Mayo should be a pan-american holiday! --Light: A History! http://wlym.com
